To au whom t may concern;

Be it known that I, Mosn WILUscHE- wITsoH, a subject of the Russian Emperor,

and resident of Nischninovgorod, Kanavino,

Russia, have invented certain new and useful Improvements in Apparatus for Producing Catalysts, of which the following is a specification.

My invention relates to improvements in apparatus for producing catalysts which are adapted for use in contact processes of various kinds, and which are particularly designed for use in processes of oxidizing and reducing fats. And the object of the improvements is to provide an'apparatus by means of which a particularly active catalyst can be manufactured in an economical way.

For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawings in which the same letters of reference have been used in all the views to indicate corre# sponding parts.

In said drawings Figure 1 is a diagrain-- matical side view partly in section, and Fig.

2 is a cross-section taken on the line 3 3 of4A Fig. 1.

In the example shown in the drawings the apparatus consists of a cylindrical drum b mounted to rotate 0n 'rollers m and provided with a heating jacket 0. The said drum is charged through an inlet-opening 'n with a prevlously prepared mixture of an insoluble, porous, inorganic carrier, such for example as clay, kieselgulir, pumice-stone, etc., with a suitable contact-substance, such as copper, iron, nickel or the like, which has been dissolved by an acid, such as sulfuric acid and converted into the carbonate by means of sodium-carbonate. To one of the end plates of the drum a tubular shaft cis secured, the free end of which is guided in a stutling-box 7c provided in a lateral stud of an upright tubular receptacle d. On the said lshaft a spur-gear g is mounted which is in mesh with a pinion q1 adapted to be rotated by means of a belt ulley a". By means ofthe gearing g1, g te drum b is slowlyrotated, and during such rotation it is heatedto "about 500o C. Hydrogen is then forced into the drum through a pipe a, located coaxially within the hollow shaft c and connected at one end with a supply-tube z'. The hydrogen passes through the mateinto the drum by means of a pump h. The

water produced by the reduction is condensed in the coil f from which it is conducted into the vessel d from which it is discharged through a goose-neck overiowpipe e. When the reduction is iinished, n0 further water liows from the vessel d. In the example shown, the dustcollector 9 by v means of which the hydrogen escaping from the drum is prevented from .carrying along the particles of dust is constructed in the form of a spiral conveyer l that extends freely aroun the tube a but rotates with the hollow shaft c. VThe dust moves through the hollow shaft c in the direction of the arrow 10 and owing to the difference in the speed of the gases anddust the'latter is deposited on the bottom of the shaft c, and returned into the drum by the conveyer 1, which is rotated in a direction opposite to the direction of motion of the gases.

1. In an apparatus for producing a catalyst, thecombination, with a rotary drum, of means for supplying a reducing gas to said drum, means for withdrawing the seiid gas and the gases produced by the reaction from said drum, and means for removing the foreign matter. from the gases withdrawn from the drum,'and returning said matter to the drum, and means for returning the reducing gas to the drum.

' 2. In apparatus for producing a catalyst, the combination, with a rotary drum, of means for supplying a reducing gas to said drum, means for withdrawing the said gas yand the gases produced by the reaction from said drum, and means for removing the dust from the gases withdrawn from the drum, and returning the dust to the drum, and means for returning the reducing gas to the drum. v

3. In apparatus for producing a catalyst, the combination, with a rotary drum, of

means for supplying a reducing gas to saidl drum, means for withdrawing the said gas and the gases produced by the reaction from 'said drum, means. for removingthe dust from thegases withdrawn from the drum, 5 and means for returning the dust to the drum. f

4., In apparatus for producingia catalyst, the combination, with a rotary drum, of means for supplying a reducing gas to said drum, means for withdrawing the said gas and the gases produced by the reaction from said drum, means for drying and revivifying the gases withdrawn from the drum, and means for returning lthe dried 15 and revivified gas to the drum.

5. In apparatus for producing a catalyst, the combination, with a rotary drum, of means for supplying a reducing gas to said drum, a tube connected with said-drum, and a screw-conveyer located within said tube and adapted to separate the dust from the ases withdrawn from the drum, and means or returning the dust into the drum.

In testimony, that I claim the foregoing as my invention, I have signed my name in 25 presence of two subscribing witnesses.
